OF FAIRMONT, llqINNES'OTA, Av CORPORTION-OF WHEEL.

Application led January 31, 1928. Serial No. 616,065.

To all whom t may concern:

Be it known that I, l/VALTER F. KAsPnR, a citizen ofl the United States,resident of Fairmont, county of Martin, and State of Minnesota, haveinvented certain new and useful Improvements in YWheels, of which thefollowing is a specification.

The object of my invention is to provide a wheel composed of a rim and ahub-supporting member pressed preferably from sheet metal and rigidlysecured together to form a light but strong and durable twopiece wheeland one that is particularly adapted for railway motor cars.

A further object is to provide a wheel of the type described which canbe easily and quickly assembled and when one member becomes worn orbroken can be taken apart and a new piece substituted for the worn orbroken member, thereby avoiding the necessity of throwing the entirewheel aside.

Other objects of the invention will appear from the following detaileddescription.

The invention consists generally in various constructions andcombinations all as hereinafter described and particularly pointed outin the claims,

In the accompanying drawings forming a part of this specification,

Figure 1 is a side view of a wheel embody-H ingmy invention;

igure 2 is a sectional View on the line Q-Q of Figure 1.

In the drawing, 2 represents the rim of the wheel formed of one piece ofmetal, preferably sheet steel, pressed into a circular form with a: railflange 3 provided on one edge. At the other edge of the rim, an inwardlyturned ange e is formed extending preferably around the wheel. A hub 5is provided having a bearing 6 for the axle, and a radial flange 7provided preferably intermediate to the ends of the hub. A sheet metalsupport 8, preferably of pressed steel, has a shoulder 9 formed in itsouter portion to receive the edge of the flange 4; the outer edge ofsaid support being seated on the inner surface of the flange and rigidlysecured thereto by suitable means such as bolts 10.

From a point near the shoulder 9, the support 8, preferably disc-like inform, and forming the spokes of the wheel, extends obliquely to thecenter, and near the center has an annular flanged portion 11 enclosinga central opening through which the hub projects, said flanged portionbeing seated against the annular flange 7 and rigidly secured thereto bysuitable means such as rivets 12.

For the purpose of strengthening the sheet metal support, to resistcrushing stresses, l prefer to provide a series of radially extendingribs 13 pressed in the metal when the support is formed; said ribsforming correspondingly shaped grooves on one side in which lugs 14provided at intervals on the flange 7 are seated, thereby locking thehub and its support against a relative rotary movement. The support alsohas openings 15 therein extending radially; these openings being formedwhen the plate is pressed out, and reducing to some little extent 'theweight of the wheel and the amount of metal in the hub supporting plate.

The advantages of this type of wheel will be immediately apparent. Incase of wear or breakage of the rim, the bolts 10 can be easily andquickly removed and a new rim substituted for the worn one, without thenecessity of casting the entire wheel aside. The parts being pressed bymeans o-f suitable dies, the wheel sections will all be interchangeableand the wheels can be quickly and easily assembled without adjusting orfitting.

l claim as my invention:

1. A wheel comprising a metal rim having an inwardly turned flange, aplate having an outer edge seated against said flange, and a shoulder toreceive the edge ofk said flange, said plate extending diagonally from-a point near said flange to the center of the wheel and having acentral orifice, and a hub mounted in said orifice.

2. A wheel comprising a metallic rim, a plate fitting within said rim,and removably secured at its outer portion thereto, said plate having acentral orifice, a hub fitting within said orifice and having a flangeagainst which said plate is seated, means for securing` said plate andflange together, said plate having radial grooves therein, and said hubflange having lugs to enter said grooves.

3. A Wheel comprising a sheet inetal rim having an outwardly projeotingrail-engaging flange on one edge and an inwardly turn-ed fia-nge at itsopposite edge, a metal disk fitting Within said rim and having a centralopening, a hub fitting Within Said openingI and secured therein, said;disk eX- tencling diagonally from said huh to said inwardly turnedflange and having a surface fitting the surface of said flange, andmeans Securing Said -rlfisk and flange together.

In Witness whereof, l have hereunto sei; my hand this 2'? dajvv o'lJanuary 1923.
